Abstract
Sn-doped silicate fibers exhibit extremely high photosensitivity when exposed to 248Â nm KrF excimer laser. Electron micrograph probing has shown that nanoscale phase separation occurs in fibers and fiber preforms after UV exposure. This phenomenon has been observed only in SnO2-doped germanosilicate and phosphosilicate fibers and fiber preforms when the SnO2 concentration is high. At low SnO2 concentrations no phase separation has been observed. SnO2 codoped glasses are the first optical fibers to exhibit phase separation.
